Could you possibly upload another version of the video, but this time all the trails are the Nyan Cat trail and everything makes the Nyan Cat song when it's moving? Even the Cheetah, but only when it's moving.

Using the 3.8 codebase I added ribbons to my projectiles and have noticed a strange side effect - shooting bullets into the terrain leaves a RibbonNode object at the point of impact for each projectile. Jump into mission edit mode after shooting some of these into the ground to see them. I modified the projectile.cs onExplode and onCollision script files to delete the ribbon. Seems to work but then thought about the projectiles that are shot into the air and hit nothing - are those ribbons being deleted when the projectile gets cleaned up. Checked the projectile.cpp code and added similar code to Projectile::onRemove() to check for the ribbon when the projectile gets deleted but this is sometimes crashing..not sure if removefromScene or Parent::onRemove handle the ribbon or not. Not sure of the implications of having tons of ribbonodes laying around but it can't be good. Anyone else notice this?
